Abstract

1446670 Mineral-mining machines; dust suppression means Gebr EICKHOFF MASCHINENFABRIK U EISENGIESSEREI mbH 16 Dec 1974 [20 Dec 1973] 54204/74 Heading E1F In a mining machine in which a sprinkler device is associated with a cutter drum 3 of the machine to wet mineral mined by the cutter to suppress dust associated with the mineral the pipe 15 supplying liquid to the device is provided with a valve 14, which is caused to close when the machine is stationary, and with a control that will adjust the degree of opening of the valve as a function of the rate of feed of the machine. Preferably a pulse generator 5, 7 is so associated with the haulage winch 6 of the machine that it will supply pulses in proportion to the speed of rotation of the winch to act on a regulator 9 on which also acts a device 11 controlled by the current flowing in the circuit of the drive motor of the cutting drum, the regulator controlling the actuating mechanism 13 of the valve 14.
